SLIDE BUCKLE.

Application filed July 18,

This invention relates to an improvement in slidebuckles and particularly to buckles especially adapted for use in overalls suspenders, the object being to provide a slidebuckle having superior capacity for holding the Web against the various strains and stresses to which it is subjected in use.

A further object of this invention is to. produce a structure having a maximum webgripping ability and of such character that the eyes at the respective ends of its webdeflecting bar will not abrade the material of the garment to which the buckle is attached.

WVith these objects in view, my invention consists in a slide-buckle characterized by having its web-deflecting or cross-bar flattened to a substantial degree, wholly or in part, between the eyes at its respective opposite ends in a plane perpendicular, to the axes thereof and transverse to the plane of the buckle-structure. I

My invention further consistsin a slidebuckle characterized as above and having certain other details of construction and arrangement of parts as will be hereinafter described and particularly recited in the claims. r

In the accompanying drawings:

Fig. 1 is a face view of a buckle embodying my invention Fig. 2 is an under edge view thereof;

Fig. 3 is a sectional view thereof on the line 33 of Fig. 1;

Fig. 4 is a similar view on the line l4 of Fig. 1; I v

Fig. 5 is a view corresponding to Fig. 4 but showing a deflecting-bar of undulating form;

Fig. 6 is a face view of a slidebuckle provided with a deflecting-bar made of square wire; and

Fig. 7 is a sectional view on the line 7 of Fig. 6.

portions assist in a large degree in holding the webbingand further provide a convenient surface upon which decorations, tradenames, etc., may be impressed.

Coming now to the novel feature of my invention, I employ a web-deflecting or cross-' surfaces located in planes perpendicular to j the axes of the said eyes and hence in planes transverse to the plane of the buckle-frame.

The flattening of the bar 17 as above described results in Widening the central portion thereof to form a web-deflecting reach 22 which overhangs to a considerable de gree the top and bottom bars 10 and 11 of the frame, as clearly shown in Fig. 3, so that when a piece of webbingisthreaded through the buckel, it will receive the maximum amount of deflection and as a result will be, very firmly gripped. Furthermore, the flat tening of the bar as described,not only provides a deflecting-reach of superior gripping capacity due to its substantially polygonal form in crosssection, but also greatlystiifens it and increases its ability to resist strains crosswise to the plane ofthe. buckle-frame,

which is the direction in which the major strains occur.

Preferably andas shown in Figs. 1 to 5 inclusive, the web-deflecting bar isformed from a piece of round wire so that when the same is flattened between its end-eyes, the latter will be of such rounded form as to avoid the chafing of the garment ,to which the buckle is attached.

If desired and as shown in Fig. 5, the de- I fleeting and gripping capacity of j the bar 17 may be further increased by imparting to it an undulating form. I

gular form in cross-section. A web-deflecting bar of this form has the advantage of providing a well defined edge for co-action with the webbing, but as above noted I prefer to employ the round wire for the purpose, since it provides smooth rounded loops,

. In Fig. 6 I have shown the bar 17 formed from a p ece of wire having initially rectana deflecting-bar formed of a single piece of wire folded at its respective opposite ends to form eyes adapted to encircle oppositely.

located bars of the said frame and flattened to a substantial degree between the said eyes in a plane perpendicular to the axes thereof and in a plane transverse to the plane the said frame.

2. A slide-buckle comprising a substan tially-rectangular frame having parallel upper and lowcr bars and parallel side bars; and a deflecting-bar formed of a single piece of wire folded at its respective opposite ends to form eyes encircling the respective side bars of the said frame and flattened to a substantial degree between the said eyes in a planeperpendicular to the axes thereof, the flattened portion of the-said deflectingbar extending transverse to the plane of the frame in position to act iii-conjunction with theupp'er and lower bars thereof to deflect and hold a piece of webbing.

3. A slide-buckle comprising a substantially-rectangular frame having parallel upper and lower bars and parallel side-bars; and a deflecting-bar formed of a single p ece of wire folded at its respective opposite 0 ds to form eyes encircling the respective sidebars of the said frame and continuously flattcned to a substantial degree between the said eyes in a plane perpendicular to the axes thereof, the flattened portion of the said deflecting b r extending transverse to the plane of the frame position to act in conjunction with the upper and lower bars thereof to deflect and hold a piece of webbing.

4. A slide-buckle comprising a substantially-rectangular frame having parallel upframe in position to act in conjunction with.

the upper and lower bars thereof to deflect and hold a piece of webbing; whereby smooth rounded n n-abrading c2-;posedeyes are located at the opposite ends of a deflecting-bar of, substantially polygonal form in cross-section.

tially-rectangular upper and lower bars andparallel side-liars; and a deflecting-bar of undulatin form in a: plane transverse to the pltldlOt the said frame and folded at its respective opposite ends to form eyes encircling the respective side-bars of the frame and flattened to a sub stantial degree between the said eyes in a plane perpendicular to the axes th e the flattened portion of the said detecting bar extending transverse to the plane of the frame in position to act in conjunction with the upper and lower bars thereof to deflect and hold a. piece of webbing.

In testimony whereof, I have signed this specification.
